One of the strong candidates to win the IOC's presidential election next week says meeting with U.S. President Donald Trump should be high on the winner's agenda.

The signatories to an open letter calling for IOC action on climate change range from Australia's most decorated Olympian, swimmer Emma McKeon, to Cyrille Tchatchet II, a weightlifter who represented the refugee team at the Tokyo Olympics in 2021.

More than 400 athletes, including more than 20 Canadians, speak up about threat of climate change to both the Winter and Summer Olympic Games.

Just days before the International Olympic Committee (IOC) elects a new president in Greece more than 400 athletes on Friday called on the future leader of the body to strengthen its action for the environment.
